Hi, If no one objects, I might clean up - i.e. permanently delete - all non-trusted users on the relax wiki: http://wiki.nmr-relax.com/index.php?title=Special:ListUsers&offset=&limit=500 There are a large number of spam bots sitting there that are blocked from doing anything, and it would be good to clear them out. If you have an account but are not trusted yet, unlikely as most of the non-trusted users have typical spam bot names, please respond to this email to have your wiki account trusted. To improve the wiki user registration process, I have installed the customUserCreateForm extension: http://wiki.nmr-relax.com/index.php?title=Special:UserLogin&type=signup https://www.mediawiki.org/wiki/Extension:CustomUserCreateForm Well, more like manually created the extension. I have included a new text section: """ Editing the wiki To be granted editing access to the relax wiki, please send a message to the <a href="http://www.nmr-relax.com/communication.html#relax-users">relax-users mailing list</a>. This is to verify that you are not a spam bot automatically creating an account. Please include a link to your research group's website, or equivalent, to help with the verification process. This measure was taken due to excessive and uncontrollable spamming of the wiki. """ This should significantly clarify the process. Regards, Edward
